c-将数学库链接到visual studio代码GCC

Question

我正试图将数学库链接到visual studio代码GCC附带的C调试器。当我使用makefile时，我想模仿参数-lm的作用。据我所知，我可以使用下面显示的launch.json文件来完成此操作。

{
"version": "0.2.0",
"configurations": [
{
"name": "gcc - Build and debug active file",
"type": "cppdbg",
"request": "launch",
"program": "${fileDirname}/${fileBasenameNoExtension}",
"args": ["nums"],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
],
"preLaunchTask": "C/C++: gcc build active file",
"miDebuggerPath": "/usr/bin/gdb"
}
]
}

我查阅了文件https://code.visualstudio.com/docs/cpp/launch-json-reference.我能找到的最接近的东西是"；miDebuggerArgs"；。我尝试将行CCD_ 1添加到"；配置"；列表，但它不起作用。有什么建议吗？

您发布了launch.json文件。转到tasks.json并在参数中添加-lm。

{
"version": "2.0.0",
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: gcc build active file",
"command": "/usr/bin/gcc",
"args": [
"-fdiagnostics-color=always",
"-g",
"${file}",
"-o",
"${fileDirname}/bin/${fileBasenameNoExtension}",
"-lm" 
],
"options": {
"cwd": "${fileDirname}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"isDefault": true,
"kind": "build"
},
"detail": "compiler: /usr/bin/gcc"
}
]
}
